DE1125313B - Continuous tread sole, especially made of rubber, intended for footwear - Google Patents

Description

The invention relates to a continuous profile sole intended for footwear, in particular made of rubber. Known soles have, from their underside, transversely to the longitudinal direction of the sole, one behind the other arranged, sawtooth-like ribs in profile, which prevent the sole from slipping to prevent wet ground. If the ribs are only inclined in one direction, the The risk of slipping is largely eliminated in this, but it is still in other directions possible. You have therefore already the sawtooth profiles in the individual sole areas according to different Directions inclined. In-depth tests have shown, however, that these soles are by no means are sufficiently non-slip. Because the ribs, which are inclined in both directions, are one behind the other when viewed in the longitudinal direction of the sole are arranged and the step with the sole on the floor never with its entire surface occurs, only the ribs arranged in one direction are often effective, so that the same Disadvantages as in the embodiments described above result.

In order to avoid the risk of slipping on all sides and to enable a really safe step, has according to the invention each individual one of the sawtooth profile ribs arranged one behind the other longitudinally their transverse extension from one sole edge to the other individual sections with forward and individual Sections with a backward sloping sawtooth profile. Even if the appearance with the sole only with part of the same, ribs on the floor are certainly supported in different directions so that prevents any slipping in the walking direction as well as in the opposite direction will.

According to a further feature of the invention, the sawtooth profile ribs are in the edge area of the sole inclined in one direction, while in the middle part of the sole it is inclined in the opposite direction. It is useful if the sawtooth profile ribs located in the edge area and inclined in one direction form a self-contained edge strip, which is located in the middle part of the sole, framed sawtooth profile ribs inclined in the opposite direction. Preferably are the individual sawtooth profile ribs located in the edge area or in the edge strip of the sole to the individual sawtooth profile ribs on the inside, seen in the longitudinal direction of the sole, offset from one another arranged.

1 shows a plan view of the underside of the shoe sole according to the invention;

FIG. 2 shows a section along the line II-II in FIG. 1; FIG. 3 shows a section along the line III-III in FIG. 1.

The profile sole 1 is provided with a closed edge strip 2, the sawtooth profile ribs directed backwards 3 has. This edge strip 2 comprises the central part 4 of the profile sole 1, in which saw number profile ribs 5 are also arranged. These ribs 5 are opposite to the ribs 3 after directed forward. This type of arrangement of the teeth against one another makes a particularly non-slip one Reached the sole. The sawtooth profile ribs 3 located in the edge strip 2 of the profile sole 1 are towards the inside located ribs 5, viewed in the longitudinal direction of the sole, are arranged offset to one another.

PATENT CLAIMS:
1. For footwear specific, continuous profiled sole, in particular made of rubber, which is provided on its underside with transverse to the longitudinal direction of the sole, arranged one behind the other, sawtooth-like in profile, the sawtooth profiles of which are inclined in different directions in individual areas of the sole, characterized in that each individual saws arranged one behind the other 209 518/152 tooth profile ribs along their transverse extent from one sole edge to the other individual sections with forward and individual sections with a backward sloping sawtooth profile. 2. Profile sole according to claim 1, characterized in that the sawtooth profiles (3, 5) in the Edge area of the sole (1) in one direction, in contrast in the middle part (4) of the sole are inclined in the opposite direction. 3. Profiled sole according to claim 2, characterized in that in the edge region of the sole (1) located, in one direction inclined sawtooth profile ribs (3) form a self-contained edge strip (2), which in the middle Sawtooth profile ribs (5) located on the sole part (4) and inclined in the opposite direction framed. 4. Profile sole according to claims 2 and 3, characterized in that the individual, im Edge area or in the edge strip (2) of the sole (1) located sawtooth profile ribs (3) to the individual, internally located sawtooth profile ribs (5), seen in the longitudinal direction of the sole, offset are arranged against one another.
